Investigate How To Change the Sound of Musical Instruments

Musical instruments are an important part of our lives, whether we play one or not.  Music can be a powerful part of our lives.

A guitar makes sounds when we pluck or strum the strings. The hollow body of the guitar amplifies the sounds (makes them louder).

Some other stringed instruments also have a hollow body, like this violin.

When the strings vibrate, the vibrations pass into the rest of the body of the instrument and come out of the sound hole.

Sound holes are usually different shapes in different stringed instruments.

The pitch changes with the thickness, length and tightness of the strings.

OK, with those thoughts in mind, let's have a look at the science of sound and how musical instruments can help us to understand that better.
